Background technology
Capacitance touch screen may be provided at the front of display to form touch control display system, its generally comprise transparency carrier and
Touch-control circuit, the main body of touch-control circuit is generally the sensing matrix formed by multiple first and second electrode crossings, when finger touches
When sensing some position of matrix, the electric capacity (such as direct-to-ground capacitance or interelectrode capacitance) of its corresponding first and second electrode can occur
Change, thus, according to this capacitance variations and certain detection means, it is possible to achieve the touch sensible of finger.
First and second electrode is typically formed by same transparent conducting film figure, its need using certain bridging design come
Ensure respective conducting of first and second electrode in cross-point locations, in cross-point locations, specifically：First electrode can be set
To disconnect to allow second electrode to continue through, and cross-over block is set on the first electrode, and is further disposed across insulation
The conducting bridge of cushion block, the first electrode that will be switched off by conducting bridge connect；It is of course also possible to above-mentioned conducting bridge is first set,
Cross-over block and first and second electrode are set gradually again, to form the bridging structure to turn upside down.
Above-mentioned conducting bridge needs graphically to be formed by another layer of conductive film layer, and its material or thickness are with forming induction electrode
Transparency conducting layer is not consistent, and its reflectivity to light is typically bigger so that this conducting bridge is in high-brightness environment, such as too
Naked eyes are easily under sunlight to be perceived, and cause certain vision to disturb the display picture of display.
At present, it is thus proposed that the scheme of conducting bridge directly " melanism " solves the above problems, for example, using reflectivity more
Low conductive material makes conducting bridge, or in the conductive film layer for forming conducting bridge sandwiches certain low reflection layer, these
Scheme is related to the internal structure for changing conducting bridge material in itself and touch-control circuit layer, and not only the performance of touch-screen can be made
Into certain influence, its manufacture craft is also more complicated, thus its application effect is not ideal.
The content of the invention
To provide a kind of capacitance touch screen for reducing vision interference, it can not only solve to lead the purpose of this utility model
The problem of electric bridge reflectivity is higher, and the performance of touch-screen will not be impacted, also it is relatively easy to make, used technology
Scheme is as follows：
It is a kind of to reduce the capacitance touch screen of vision interference, including first substrate and it is arranged on first substrate outer surface
Touch-control circuit layer, it is characterized in that:The touch-control circuit layer include the induction electrode that is formed by the first conducting layer figure and by
The conducting bridge for being used for induction electrode bridging that second conducting layer figure forms, the outside of the conducting bridge, which is provided with, blocks bar, institute
State and block bar and formed by the extinction membrane graphic of black or dark color, the conducting bridge is in described and blocked within the projection of bar.
In this manual, " outside " refers to touch-screen when in use, and the film layer such as first substrate, it is closer to operator
Manipulation finger side, it is on the contrary then be referred to as " inner side ".
Above-mentioned first substrate can be glass substrate, such as the glass substrate that thickness is 0.1-2.0mm.First conductive layer can be with
For nesa coating, such as indium tin oxide films (ito film), it is different first of multiple directions that it, which is typically patterned immediately (such as photoetching),
Electrode and second electrode, first and second electrode are that (in the driving of the touch-screen of reality, first and second electrode can for the induction electrode
Respectively signal transmitting, receiving electrode, are considered induction electrode herein), it intersects and forms induction arrays.Comprising leading
The bridging structure setting of electric bridge is on the crosspoint of first and second electrode, to allow first electrode and second electrode in respective direction
On conducting, in cross-point locations, specifically：First electrode can be disconnected to allow second electrode to continue through, and the
Cross-over block is set on one electrode, and is further disposed across the conducting bridge of cross-over block, first will be switched off by conducting bridge
Electrode connects；Or above-mentioned conducting bridge can also be first set, then cross-over block and first and second electrode are set gradually, with shape
Into the bridging structure to turn upside down.Conducting bridge is formed by the second conducting layer figure, and the second conductive layer can be the conductions such as ito film
Film layer；It is preferred that the second conductive layer is metal film, although metal film reflectivity is very high, in the case where covering the coverage of bar, it is high anti-
The rate of penetrating can't cause vision to disturb, and its resistivity is smaller, thus conducting bridge can be made to it is more tiny so that
Covering bar can also correspondingly reduce, and thereby reduce coverage bar and display display content is blocked；Specifically, the gold
It can be stable and electrically conductive good single or multiple lift, the metal such as copper film or " molybdenum niobium-aluminium neodymium-molybdenum niobium " three-layer alloy film to belong to film
Or alloy film layer.
The bar that blocks can use the black of easy precise pattern or dark light absorbent to be made；Preferably,
The bar of covering is made by the photosensitive resin of black or dark color；Further preferably, the black or the light of dark color
Quick resin is by the negative photosensitive resin solidified after ultraviolet light, and chemical property is more after coverage bar is formed for it
Add stabilization so that coverage bar is not allowed easy to fall off.What the photosensitive resin by black or dark color was made blocks bar, its thickness
More than 0.5 μm is could be arranged to, to ensure that it has enough coverage effects.
The size for blocking bar is generally set blocks conducting bridge enough.Preferably, it is described block bar with
The conducting bridge has consistent profile, for example, block bar profile it is identical with the profile of conducting bridge or more bigger than conducting bridge,
For example, the profile that the profile for blocking bar can be conducting bridge expand in 10 μ ms and form, thus, it is possible to ensure to block bar compared with
The small display content without egregiously blocking display.
Preferably, the conducting bridge and its side of bar and touch-screen is blocked into the angle between 30-60 °.Due to display
Single primary colors that multiple sub-pixels (such as R, G, B sub-pixel) of same primary colors are generally constituted parallel to the side of display or touch-screen is straight
Line, by conducting bridge and its block bar and be arranged to the side of touch-screen into the angle between 30-60 °, i.e. its major axis or extending direction
With the side of touch-screen into the angle between 30-60 ° so that blocking projection of the bar in the pixel blocked can be more across it
The sub-pixel of individual primary colors, the sub-pixel of particular color is only blocked and so that colour cast occurs in related pixel to avoid blocking bar ---
This colour cast is also easily perceived by naked eyes, so as to cause vision to disturb.
Preferably, the touch-control circuit layer outer side covers have a planarization layer of transparent insulation, it is described block bar be arranged on it is flat
On the outside of smoothization layer.Above-mentioned planarization layer can be patterned photosensitive resin layer, and it can reduce the cross-over block of bridging structure
Caused difference in height, to avoid when covering bar and being superimposed with cross-over block, it is highly excessive and cause unstable in structure；
In addition, when the first conductive layer is ITO layer, the surface of photosensitive resin layer is typically smooth compared with the first conductive layer, can reduce making and hide
Residual of its film layer in non-coverage bar position when covering bar so that it is higher that this touch-screen makes yield.
Preferably, in addition to contraposition part, the contraposition part are arranged on the periphery of touch-screen, and it comprises at least conductive by second
Layer pattern form to bit patterns.Thus, when making coverage bar, aligned using contraposition part so that cover bar energy
Enough outsides for being more accurately in conducting bridge.
Preferably, in addition to second substrate, second substrate are arranged on the outside of first substrate so that the bar that blocks is by clamping
Between first and second substrate.Thus, the raised bar that blocks is not easy to be damaged (during as touched by the protection of second substrate
Wiped off by nail).Further, substratum transparent is provided between first and second substrate, the bar that blocks is soaked by the glue-line
Not yet, above-mentioned glue-line can be transparent liquid or solid-state glue-line, and it can further reduce the reflection for blocking bar surface so that hide
Cover that bar is darker to be more difficult to think that naked eyes are perceived, thus its to reduce the effect that vision is disturbed more preferable.
Compared to prior art, capacitance touch screen provided by the utility model, it is covered bar and is arranged on the outer of conducting bridge
Side, conducting bridge are among the projection for covering bar, thus have coverage effect to conducting bridge, it is anti-can to efficiently solve conducting bridge
Penetrate the higher caused vision interference problem of rate.In addition, the outside of touch-control circuit layer is in due to blocking bar, it is not related to
And the internal structure of conducting bridge material in itself and touch-control circuit layer, therefore the performance of touch-screen will not be impacted (i.e.
It is made to it thicker).In manufacture, it need to only add the processing step for making and covering bar on the processing procedure of existing product, and
